I'll add a vote for spending a little more and getting a whole lot more capability for the future. I bought an Apprentice 15e, great plane by the way, and upgraded the 5 channel Spektrum transmitter it came with for a 6 channel. Now I have all the transmitter I'm ever likely to need. I recently added an AnyLink and can now fly just about anything using my one transmitter. On the other hand, I had a very bad experience with Hobby King/Turnigy equipment. I bought two receivers and neither of them would turn on. I can't say much about the transmitter because I never had a receiver to use it with. I'd stay away from them until they get the quality control straightened out.

About your Champ, I have one and love flying it. I've flown it in winds of 4 mph or so with no problem. I'm saying this because I don't know how much wind you think you should be able to fly in but even the larger foamies like my Apprentice have their limits. I flew the A for the first time on a day with winds of 10+ mph and the first minute or so after take off got my pulse rate up.
